What are some mini self-care that we can fit into our existing routine?

I like to listen to my favorite music or podcast on my commute, with uplifting scent (air freshener) in my car.

I like using aroma-therapeutic products in the shower. And Cinnamon toothpaste in the morning (yum!)

The reason I ask for more ideas is, right now, it causes me stress to "schedule" extra time for self-care like going to the salon since I'm dealing with works-shift schedule uncertainty.

So I wanted to know more things that I could incorporate into my daily routine.
